Abstract: A method of making an absorbent core structure includes meltspinning at least one layer of fibrous material. A first amount of superabsorbent material is deposited on the layer of fibrous material. A first portion of the layer of fibrous material is folded over the first amount of superabsorbent material. A second amount of superabsorbent material is deposited on the layer of fibrous material. A second portion of the layer of fibrous material is folded over the second amount of superabsorbent material. Additional embodiments involve rolling the fibrous material and/or densifying one of the layers relative to the other.

Abstract: An absorbent core structure having at least one acquisition region, at least one distribution region, at least one storage region. The acquisition region being constructed from a fibrous material. The acquisition region having a relatively low density from about 0.018 g/cc to about 0.20 g/cc. The at least one distribution region being constructed from the fibrous material. The distribution region being consolidated to have a relatively medium density from about 0.024 g/cc to about 0.45 g/cc. The distribution region being in fluid communication with said acquisition region. The storage region being constructed from the fibrous material. The storage region being consolidated to have a relatively high density from about 0.030 g/cc to about 0.50 g/cc. The storage region being in fluid communication with the distribution region. The fibrous material may be folded to form said absorbent core structure. The fibrous material may be rolled to form the absorbent core structure.

Abstract: A method of making an absorbent core structure includes meltspinning at least one layer of fibrous material. At least one valley is formed separating at least two peaks in substantially parallel rows in the layer of fibrous material. A first portion of the first layer of fibrous material is folded over a second portion of the first layer of fibrous material. A least part of the first layer of fibrous material is densified.

Abstract: A method of making an absorbent core structure includes meltspinning at least a first layer of fibrous material having a plurality of first portions and a plurality of second portions. A superabsorbent material is deposited between the respective first and second portions of the first layer. The first portions of the first layer are moved with respect to the second portions of the first layer so as to at least substantially encapsulate the deposited superabsorbent material between the respective first and second portions.

Abstract: Methods, apparatus and disposable hygienic absorbent products involving melt processing a synthetic resin or resins, such as a thermoplastic, in an in-line process. The melt processing operations can be melt spinning processes such as spunbonding and/or meltblowing the resin(s). One or more through air bonders are used in the process to provide bonding between fibers or filaments while retaining the liquid management properties of the fibers or filaments in the disposable hygienic absorbent product. Other melt processing operations, such as film extrusion, may also be used to form one or more layers in the disposable hygienic absorbent product.
